FLOOR CONSTRUCTION.

Application filed Gotoher 1, 1925.

This invention which has to do generally with floors, is concerned more particularly with a cen'ientitious construction having sunken carpet panels, with means which reinforce the panel edges, and with means which provide an anchorage for the secureinent of the carpet in place. A flooring of this hind is particularly advantageous in theaters, and other public auditoriuins, where seats are arranged in rows upon a hard floor surface with strips of carpet in between and in the aisles.

F or its objects my invention aims to provide around each carpet panel a reinforcing wall which is both ineapensive to produce and install; a reinforcement which also connects with a wooden strip adjacent the carpet edges, perniitt-ing the use of nails or tacks to hold the carpet in place thereon; and a reinforcement which may he shaped and fitted for installation in places where conditions vary greatly. rlliese and other ohjects of my invention will appear from the 'description and claims to follow, taken in conjunction with the accompanying drawing wherein a preferred embodiment thereof is shown in the manner following:

Figurel which is a fragmentary sectional view through an inclined floor shows seat supports rested thereon with intervening' panels adapted for the reception of carpet;

Fig. 2 is an enlarged fragmentary detail in plan, portions of the reinforcing wall, the carpet, and underlying pad, being broken away;

Fig. 3 is a transverse section taken on line 3-3 of Fig. 2; and

Fig. d is a perspective view of one of the clips which holds the reinforcing wall in place.

My invention may be utilized in various places and for different purposes, but prohably its most advantageous adaptation is in connection with a theater floor which is ordinai-ily inclined, as suggested in 1. rlhe seats are commonly secured thereto in curved rows with aisles converging toward the front. It will conduce to a ready understanding of this invention to describe the same in connection with a floor of this general kind, and accordingly the views in the drawing show such a construction.

Upon the floor hase A is applied a cementitious surface B depressed in places to form panels and aisles C. Upon the upper floor levels B may be mounted seats D of which Serial No. 59,790.

only the supporting bases are shown. Embedded in each panel and aisle so as to be flush therewith are carpet strips 5, preferahly of wood, which extend around the edges thereof.

According to this invention, the panel and aisle walls are protected by a moulding 6 having a channel cross section with inturned flanges 7, as best shown in Fig. 3. Such a moulding may be produced conveniently from a square tube of metal by sawing out the greater portion of one side thereof,

.i thus providing a slot which, in practice, is

faced laterally away from the adjacent sunken lloor level. rlhese mouldings may be set in place before the floor surface is applied to its hase, and clips 8, each having a head 9 which interloclis withinthe moulding, are extended laterally therefrom for embedment within the floor surface. At the eX- tremity of each clip is a tongue 10 which anchors the clip in place, and adjacent its head I have provided a wing 11, which is turned laterally to lie adjacent one edge of the carpet strip 5. A hole 12 is formed through the wing to accommodate a nail 13 which may be driven into the carpet strip, In this manner I am enabled to assemble the several mouldings iiXedly upon the carpet strip prior to application of the material forming the floor surface. A pad 14 of felt or other desirable material is thereafter laid within each panel and aisle, following which strips of carpet E are applied thereon. The carpet may be fastened in place by nails or tacks 15 (see F ig. 3) whichare driven into the strips 5 in the customary manner.

The protection afforded to the panel walls by the mouldings 6 is such as to prevent any breaking down of the edges thereof. A flush and neat connection therewith results from this construction which avoids any obstruction such as might cause a person to trip. rlhe length of the moulding may be determined according to what is found most advantageous, and where it is necessary to join the ends of two of them, a dowel 16 may be used, as suggested in Fig. 2. Also mitered corner pieces 17 may he used wherever necessary, being joined to the proximate mouldings by dowel pins in the manner just mentioned. l

According to this invention, I provide a very advantageous reinforcement to the abrupt connecting wall of a two-level door. The clips which serve to anchor the mouldings inA place are slidable therein to any desired position, and their attachment requires only that they be turned slightly during the inserting movement. It is manifest, of course, that the illustrative structure hereinbefore described may be modified within considerable limits without sacrifice of the improvements characterizing this invention, the scope of which is defined in the claims below.

l claim:

1. A floor having a surface in which is a depressed panel, a carpet strip arranged flush within the panel and adjacent they surrounding walls thereof, a moulding connected to the strip and extending upwardly therefrom to lie flush with the floor surface, and means connecting the moulding thereto, substantially as described.

2. A floor in which is a depressed panel having adjacent its edges racarpet strip flush therewith, means connected with the strip extending upwardly to protect the floor walls adjacent the panel, and clips forming a connection between said means and the floor, substantially as described.

3. A floor in which is a depressed panel having adjacent its edges a carpet strip flush therewith, a moulding connected with the strip and extending upwardly in flush relation with the floor, said moulding being formed of a plurality of square tubes arranged end to end with dowels inserted` in the joints thereof, and means connecting each moulding to an associated carpet strip and to an adjacent portion of the floor, substantially as described.

4;. A floor in which is a depressed panel having adjacent its edges a carpet strip flush therewith, sectional means connected in alignment with each other and extending upconnected to the carpet strip and extending upwardly to lie flush with the upper floor level, and means interloclred with the moulding forming a connection with the floor whereby the moulding is held in place independently of its connection wit-h the carpet strip, substantially as described.

6. A two-level floor having an abrupt connecting wall, a carpet strip flush with the lower floor level, a channel-shaped moulding rested on the strip with a top face flush with the upper floor level, and a single means of connection between the moulding, carpet strip, and floor, substantially as described.

7. A two-level floor having an abrupt connecting wall, a carpet strip adjacent the wall and flush with the lower floor level, a channel-shaped moulding rested on the carpet strip with its'open side extended laterally toward the wall and having its upper side Hush therewith, and means detachably secured to the moulding and to the carpet strip adapted also for anchorage within the floor, substantially as described.

8. A two-level iioor having an abrupt connecting wall, a carpet strip adjacent the wall flush with the lower floor level, a moulding formed of sections disposed end to end arranged adjacent the wall and iiush with the upper floor level, means connecting the ends of adjacent moulding sections in alignment, and means connecting the moulding with the licor and with the carpet strip, substantially as described.

9. A two-level floor having an abrupt connecting wall, a carpet strip adjacent the wall and Hush with the lower iioor levels, a moulding rested on the strip adjacent the wall and flush with the upper floor level, and a clip slidingly interlocked with the moulding having a wing adjacent one strip edge and adapted for embedment within the flooring, there being means passing through the wing into the strip to connect the clip thereto, substantially as described.
